Sketching User Experiences: Getting the Design Right and the Right Design by Bill Buxton Wow! Wow! Wow! I found this in the Bibliography of Business Model Generation.
This is not an easy read, so I find it hard to make it a must read. That said there are so many good ideas that are well developed and explained thoroughly. If you’re into innovation then this is a must read. I really like how much time Buxton spends relating and positioning design with respect to the other disciplines like marketing and engineering. The whole concept of sketching vs. prototyping took a while to sink in for me. I’m hoping to write more on this book. It has a good history of the iPod in it too.
Diagramming Innovation – Explore & Refine
I find that most people “want to believe” that innovation is “incremental refinement” and that some people “want to believe” that innovation is a “grand exploration”. Buxton provides to two very simple diagrams to convey these themes on page 388. I think innovation requires both. I think that is why I like Steve Blanks Customer Development Model with it’s Search (Explore) and Execute (Refine) phases.
The red lines
In fig 150 the RED Line is to emphasize how many branches were being explored at that given time in the process. …
The branches in Fig 150 are intended to represent the various alternatives that were explored in the process of arriving at the end design, which is represented by the branch at the extreme right. This is where the RED ARROW in Figure 149 begins.
